Abstract
Abstract An integrated unit in extracorporeal blood circuit includes a tank (1) internally provided with a wall in defoaming material (2) having at least one filter (11), adapted to delimit at least laterally a portion of space inside which blood coming from the patient and from the operating field inflows, and thus such as to act simultaneously as venous tank and as cardiotome, said tank (1) being connected monolithically to a heat exchanger (15) and to an oxygenator (14) adapted to be traversed by the outflowing blood from said tank (1).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
Integrated unit in extracorporeal blood circuit, characterized in that it comprises a tank internally provided with a wall in defoaming material comprising at least one filter, adapted to delimit at least laterally a portion of space inside which blood coming from the patient and from the operating field inflows, and thus such as to act simultaneously as venous tank and as cardiotome, said tank being connected monolithically to a heat exchanger and to an oxygenator adapted to be traversed by outflowing blood from said tank.
Claim 2
Dependent Claim
85 words
Integrated unit in extracorporeal blood circuit, characterized in that it comprises a tank internally provided with a wall in defoaming material comprising at least one filter, adapted to delimit at least laterally a portion of space inside which blood coming from the patient and from the operating field inflows, and thus such as to act simultaneously as venous tank and as cardiotome, said tank being connected monolithically to a heat exchanger and to an oxygenator adapted to be traversed by outflowing blood from said tank.
Claim 3
Dependent Claim
65 words
Unit according to claim 1, characterized in that the tank is provided with a connection for coupling to the aspiration line of a pump adapted to determine the circulation of the blood, the heat exchanger having an inlet connected to the delivery of said pump, and having an outlet directly connected to an inlet of the oxygenator, from which the blood returns to the patient.
Claim 4
Dependent Claim
51 words
Unit according to claim 1, characterized in that said tank is directly connected to an inlet of said heat exchanger, there being provided, at an inlet of said oxygenator, a pump adapted to determine the circulation of the blood and connected, at its aspiration, to an outlet of said heat exchanger.
Claim 5
Dependent Claim
43 words
Unit according to one or more of the preceding claims, characterized in that said tank is arranged in a position overlying a monolithic structure upwardly comprising said oxygenator and downwardly comprising said heat exchanger, and is connected thereto by means of a quick-connection.
Claim 6
Dependent Claim
32 words
Unit according to one or more of the preceding claims, characterized in that it comprises a tank cover having a connector adapted to connect the interior of the tank to the atmosphere.
Claim 7
Dependent Claim
79 words
Unit according to one or more of the preceding claims, characterized in that the portion of space delimited at least laterally by said wall in defoaming material has a cylindrical shape and is divided into two parts, a lower part being provided with an inlet connection for blood coming from the patient, and an upper part being provided upwardly delimited by a portion of said tank cover provided with an inlet connection for blood coming from the operating field.
Claim 8
Dependent Claim
56 words
Unit according to one or more of the preceding claims, characterized in that said wall of defoaming material intended to be traversed by the blood coming from the patient is provided with one filter, said material having a further part intended to be traversed by blood coming from the operating field and provided with two filters.
Claim 9
Dependent Claim
33 words
Unit according to one or more of the preceding claims, characterized in that said tank cover is connected to said tank so as to be rotatable, and with the interposition of sealing gaskets.
Claim 10
Dependent Claim
24 words
Unit according to one or more of the preceding claims, characterized in that said tank has a structure adapted to be arranged in depression.
Claim 11
Dependent Claim
36 words
Unit according to one or more of the preceding claims, characterized in that it comprises a bypass line adapted to connect the outlet connection of the oxygenator with one of the inlet connections of the tank.
Claim 12
Dependent Claim
45 words
Unit according to one or more of the preceding claims, characterized in that it comprises a mechanical safety device at the connection for the outflow of the blood from the tank, adapted to determine the closure of said connection upon any emptying of the tank.
Claim 13
Dependent Claim
141 words
Unit according to one or more of the preceding claims, characterized in that the mechanical safety device provided at the connection for the outflow of the blood from the tank comprises an elastic membrane connected to the structure of the tank and adapted to be kept, by the hydrostatic load of the overlying blood, in such a configuration as to keep open said connection and so as to move to occlude the same when said load reaches a value corresponding to a minimum level of the blood in the tank, said membrane being provided with a tab adapted to be gripped by an operator to return said membrane from the occlusion position to the opening one, and in that further comprises present a small cover adapted to limit the elastic deformation of the membrane in condition of opening of the connection.
Claim 14
Dependent Claim
105 words
Unit, according to one or more of the preceding claims, characterized in that said mechanical safety device comprises an autonomous containment structure adapted to be connected to said tank, said containment structure comprising an elastic membrane adapted to be kept by the hydrostatic load of the blood in such a configuration as to keep open the blood outlet coupling and to move to occlude the same when said load reaches a value corresponding to a minimum level of the blood in the tank, said membrane having external grip means to allow an operator to return the same from the occlusion position to the opening postion.
